Description

This event tracks the highest temperature reached in Boston on a specific date in the future. It categorizes possible temperature outcomes into distinct ranges, each corresponding to a different market resolution. The final determination relies on an official weather data source to ensure consistency.

Kalshi

The event resolves based on the maximum temperature recorded at Boston’s CLIBOS station on August 28, 2026, as reported by The Weather Company. Six distinct temperature ranges define the possible outcomes: 78° or below, 79-80°, 81-82°, 83-84°, 85-86°, and 87° or above. If the recorded temperature falls within any of these ranges, the corresponding market resolves to Yes. All markets use The Weather Company as the sole authority for temperature data, with users advised that preliminary readings may vary due to rounding or conversion differences. No other weather sources are considered official for resolution purposes.
